Drillbotics competition

Drillbotics® is an international competition for universities to design and build a small drilling rig that uses sensors and control algorithms to autonomously drill a rock sample provided by SPE’s Drilling Systems Automation Technical Section (DSATS).

Hydrocarbon & Geothermics Workgroup, a group of teachers and students of the ICI Faculty, has decided to promote participation in this international competition. We are looking for motivated and passionate people, willing to face a challenge that requires different skills ranging from mechanics, hydraulics, information technology and electronics.

European Geothermal Congress: the final countdown!

Next Tuesday, EGC2019 will start, it’s the most important event in Europe for geothermal energy stakeholders. The congress takes place every 3 years and it is organised by EGEC, the European Geothermal Energy Council, a non-profit international organization  founded in 1998 to promote the European geothermal industry.

For 2019 the EGC will be hosted by the city of Den Haag, Netherlands, between 11 and 14 of June. It will host several and various events: scientific conferences and poster presentations, specialized events for business development, traning courses, events for and from national and European policy makers, social events and side conferences for European projects. It will be a unique opportunity for Europeans working in different aspects of geothermal, whether academic, industrial or societal, to come together.

HGW will be there with two posters. One is focused on the use of a deep borehole heat exchanger coupled a ORC plant. A comprehensive thermodynamic assessment of the plants has been carried out analysing each component, including the cooling tower and ancillary equipment. The concept of energy, which is the maximum work output that could be obtained from a system, has been used to evaluate the performance of the system. Other one illustrates the implementation of Ground Source Heat Pump system in the energy plant of a 70’s sporting center in Italy. None energy upgrading on the building has been accounted and three different solution have been proposed and analysed. Then the three solutions have been compared using two different approaches: the economic analysis and the multicriteria analysis, which includes also the CO2 emissions and the primary energy consumption.

P4N – Projects for Ninfa – The water crisis of 2017 and the management of environmental systems

On 13 February 2019 a workshop on water crisis and its management occurred in the “Complesso Monumentale Tor Tre Ponti” (Latina), headquarters of Caetani Foundation.

We are proud of our students of the course “Produzione e gestione delle georisorse fluide”, who have presented the research works carried out during the semester under the guidance of Prof. Claudio Alimonti and Dott. Massimo Amodio, vice-president of the Caetani Foundation.

By virtue of the existing agreement between the Roffredo Caetani Foundation and the Pontine Pole of La Sapienza University, the Foundation has made available the “Giardino di Ninfa” Natural Monument as a “training ground” for students in order to study what happened during the 2017 water crisis.

The results regarded the analysis of the available data and the elaboration of possible models of the prevision and management of the water crisis. A group of students has analyzed the problem with a wide-scale approach considering the recharge basin of the Ninfa spring system and the possible interactions with the intake systems managed by Acqualatina. Another group faced the Pantanello park, which showed the heaviest signs during the crisis of 2017. The lakes system was modeled in order to predict critical moments and to make any decisions aimed at the system’s eco-dynamic conservation.

We believe that when the knowledge goes out from the university and it faces real problems of the territory, it is a precious opportunity both for the students, who have the chance to apply what they have studied, and for the community.

Hydrocarbons & Geothermics…our vision of the future

Global changes urge a radical transformation and improvement of energy producing systems to meet the targets of the European Energy Roadmap 2050: a secure, competitive and decarbonized energy system.

In this scenario a synergic integration of geothermal energy into the hydrocarbons fields could be a disruptive opportunity. on one side the oil&gas reservoir are not renewable and marked by high decommissioning costs. On the other side, the geothermal energy is sustainable and renewable but the cost of wells drilling is generally 50% of the field commission costs.

The opportunity is rapresented by the large amount of formation waters produced during the oil&gas extraction in the mature stage of hydrocarbons fields. those waters must be trated continuously and could not be released to the environment, but they presents often temperature greater than 50°C. Increasing the maturity of assets, the water production increases until a complete depletion of hydrocarbons. These hydrocarbons fields could be converted into geothermal ones generating different positive consequences: increase of the share of renewable energy sources; no  the cost and the impact connected to drilling new geothermal wells; no decommissioning costs for oil&gas companies; opportunity to create a positive social response in the area where the oil and gas wells are located.

We will discuss our idea during some international conferences this year. If you want to see our progress keep following us…

How the transition to renewable energies will change the global geopolitical equilibrium? IRENA tries to respond in the new report

Climate change requires, increasingly more strongly, to transform fossil fuel based energy supply into that based on renewable energy sources. This landmark transition will have consequences on the global equilibrium. New energy leaders will emerge, the energy independence of single states will increase, the distributed energy generation will reduce the energy request to the centralized grid systems. These and other effects will completely change the word as we know it today. The Global Commission on the Geopolitcs of Energy Transformation of International Renewable Energy Agency (IRENA) describes the effects of energy transformation in the repost “A new world”.

Geothermal research well at University of TU Delft

“You can do a lot with lab work and modelling, but at a certain point you really need to study what is actually happening in the ground. We need to check the models and the theory with a geothermal well in operation. Therefore, we came up with the idea of a Living Lab, a geothermal well that is not just producing hot water to heat our building on campus, but that serves as a research infrastructure at the same time”.

This is the idea of Phil Vardon,  Associate Professor at the Department of Geoscience & Engineering at TU Delft, in Netherlands. This idea is becoming reality, through the DAPwell project, the project of a geothermal well that will serve the heat for the campus buildings and will function as a living lab for scientific and educational purposes. DAPwell was first imagined by a group of TU Delft students in 2008. Now a project team is currently working on finalizing the business case and administrative issues.

Geothermal energy in Cornwall

Two wells have been drilled near Redruth, in order to produce geothermal energy from the hot rock of Cornwall. The wells are the deepest of UK (2,5 km and 4,5 km) and the power station may have the capacity of 3MW, which is about a third of a single modern offshore wind turbine or enough to power around 7,000 homes.

For further details read the article of The Guardian.
